Modifiers add custom name for quality of life

I love the Modifiers addition to capture 'variables', very useful!

A quality of life feature would be the ability to rename the modifiers much in the same way in programming in python, whereby we can give each 'modifier' or variable a meaningful name. for ex. m1 = 'color.index', m2 = 'tracknumber'

Now that I have been building up scripts keeping track of all the M1, M2, M3 etc has led to a couple of easily avoidable mistakes in my scripts.

should be easy to implement. Thoughts?
